Personally I don't fully trust VPNs, yeah they can be good at times, but that doesn't mean I trust them to secure my data, I remember when I tried using VPN to access a particular site, since my country was restricted from there, i was able to gain access at first and then later I still got banned, meaning it couldn't cover my tracks, from my end the only VPN that can assure you anonmity is TOR, I think its way better than most VPNs out there.
No. I don't think you understand how a VPN works. They are not meant to "secure your data" all; they do is mask your traffic so your ISP can't see what is going on. They can still see you are using a VPN though.
Just because 1 VPN didn't work for you doesn't mean they all are. Which VPN did you use? A VPN doesn't cover your tracks but rather obscures them. The tracks are there but you cannot see what they are.
You got a ban because the website knew you were using a VPN. WEbsites will tell you at the beginning or in their terms or even their FAQ that you will be banned for a VPN. You would also get banned while using TOR.
Who says it is better than most VPNs out there? If that was true I would be using it to stream USA content.
